【摘要】：为了科学合理地评价工作面顶板水疏放程度,分析了工作面涌水量预测值和疏放水观测值等要素,构建了顶板水疏放程度评价指标体系,划分了相应的评价等级标准,并利用AHP法确定了各评价指标的权重,建立了顶板水疏放程度的物元可拓模型。利用AHP-物元可拓模型对宁东煤田水文地质条件较为复杂的5个工作面顶板水疏放程度进行了评价,评价结果均为顶板水疏放程度好,并且各工作面已经实现了安全回采,实际情况与评价结果一致。AHP-物元可拓模型可以用于评价顶板水疏放程度,并且可以作为工作面采前水文地质条件评价的参考依据。
[Abstract]:In order to evaluate the drainage degree of roof water in working face scientifically and reasonably, the factors such as the forecast value of water discharge and the observation value of water drainage are analyzed, and the evaluation index system of roof water drainage degree is constructed, and the corresponding evaluation grade standard is divided. The weight of each evaluation index is determined by AHP method, and the matter-element extension model of roof water thinning degree is established. Based on the AHP- matter-element extension model, the roof water drainage degree of 5 working faces with complicated hydrogeological conditions in Ningdong coalfield is evaluated. The results show that the roof water drainage degree is good, and the safe mining has been realized in each working face. AHP- matter-element extension model can be used to evaluate the drainage degree of roof water, and it can be used as a reference for the evaluation of hydrogeological conditions before mining.
